to anterior and also to posterior laterals. Lateral eyes on each side 

 subcontiguous. Clypeus narrow, its width not exceeding the radius 

 of an anterior lateral eye. 



Labium wider than long. 



Lower margin of ehelicera with one tooth; upper with three of 

 which the median is largest. 



Legs slender; wellspined; tarsi scopulate but not densely so. 



Inferior spinnerets widely separated; median spinnerets moderate, 

 cylindrical. 



Genotype. — Apodrassus andinus, sp. nov. 



Related to Leptodrassus Simon, but differing in the much narrower 

 clypeus, more strongly recurved eye-rows, in having the posterior 

 median eyes decidedly farther from each other than from the laterals, 

 the tarsi moderately scopulate, and the inferior spinnerets widely 

 separated instead of connivent. 



Apodrassus andinus, sp. nov. 

 Plate 12, fig. 3-8. 



Carapace and legs light brown, the carapace and femora slightly 

 dusky. Sternum and coxae of legs beneath clearer, more testaceous. 

 Abdomen beneath light brown, above darker, dusky brown. 



Posterior row of eyes very strongly procurved, a line tangent to the 

 anterior edges of the medians being nearly tangent to the posterior 

 edges of the laterals; medians elongate (axes to each other as 8:5), 

 set very obliquely, separated by a distance equal to the lesser diam- 

 eter, closer to the laterals about three fifths as far; lateral eyes a little 

 larger than the medians (long diameters about as 9:8), about half 

 their radius from the anterior laterals to which they are subequal in 

 size. Anterior row of eyes scarcely longer than the posterior; in 

 dorsal view a little procurved, in anterior view strongly so, a line 

 tangent to lower edges of medians passing through caudal third of 

 laterals ; medians circular with diameter larger than the long diameter 

 of the laterals (10:9), three fifths their diameter apart, much closer 

 both to the anterior and the posterior laterals; laterals separated 

 from lower edge of clypeus by a distance equal to their radius or a 

 little less, the medians bv about four fifths their diameter, (Plate 12, 

 fig. 5).
